本文实例讲述了C#实现HSL颜色值转换为RGB的方法。分享给大家供大家参考。具体实现方法如下：
//This method converts the values to RGB public RgbColor HslToRgb(int Hue, int Saturation, int Lightness) { double num4 = 0.0; double num5 = 0.0; double num6 = 0.0; double num = ((double)Hue) % 360.0; double num2 = ((double)Saturation) / 100.0; double num3 = ((double)Lightness) / 100.0; if (num2 == 0.0) { num4 = num3; num5 = num3; num6 = num3; } else { double d = num / 60.0; int num11 = (int)Math.Floor(d); double num10 = d - num11; double num7 = num3 * (1.0 - num2); double num8 = num3 * (1.0 - (num2 * num10)); double num9 = num3 * (1.0 - (num2 * (1.0 - num10))); switch (num11) { case 0: num4 = num3; num5 = num9; num6 = num7; break; case 1: num4 = num8; num5 = num3; num6 = num7; break; case 2: num4 = num7; num5 = num3; num6 = num9; break; case 3: num4 = num7; num5 = num8; num6 = num3; break; case 4: num4 = num9; num5 = num7; num6 = num3; break; case 5: num4 = num3; num5 = num7; num6 = num8; break; } } return new RgbColor((int)(num4 * 255.0), (int)(num5 * 255.0), (int)(num6 * 255.0)); } //The structure that will hold the RGB Values public struct RgbColor { public RgbColor(int r, int g, int b) { red = r; green = g; blue = b; } public int red; public int green; public int blue; }
希望本文所述对大家的C#程序设计有所帮助。
